I'm using Windows Live Mail. A message I've been working on and had saved in my Draft Folder has suddenly disappeared.

When I opened Drafts the email was top of the list, being the latest, but instead of the text I had worked on appearing in the content window, there was a message indicating that there had been a problem and the content couldn't be displayed.

To  view the content anyway I was directed to click on a blue link that said "click here" or "view here" which I did but instead of opening the content up, the entry disappeared completely from the list.

I'd spent several hours working on the text, How do I recover it please?
